The bone china cup was born on the Great Isle of England in 1794. It is the result of the efforts of British potters to obtain a product as delicate as Chinese porcelain. What material is the bone china mug made of? Bone china cups are named after adding beef bone powder to the clay. Of course, sheep bone or pig bone powder can also be added, but the quality is not as good as beef bone powder, and the kiln temperature required for firing is also different, so the industry uses Bovine bone powder is used to make bone china mugs. Because the main raw material uses the bone meal of herbivores, it is also considered a green and environmentally friendly product. The formation of bone china cups mainly depends on silica, alumina and calcium oxide. The more calcium oxide there is, the better the color of bone china cups will be. There are few sources of calcium oxide in nature, and animal bone meal is a good source of calcium oxide.
The basic process of bone china cup products is to make bovine bone powder, clay, feldspar and quartz through high-temperature biscuit firing and glaze firing twice, and then you can make bone china cups without patterns. After decal paper is needed, it needs to be baked. In addition, after gold inlay, it also needs to be baked with gold fire. The important basis for distinguishing bone china cups from non-bone china cups has two most basic characteristics: first, it needs two firings to be made, that is, biscuit firing and glaze firing. Second, the content of animal bone powder accounts for at least 36%, which is the Chinese standard, the British standard is 30%, and the American standard requires no less than 25%. In this way, it is the real bone china cup, otherwise it is a low bone china cup or a non-bone china cup.
